Answer:

The answers are:

Step-by-step explanation:

Given:

Distance of Hotel and car = 163 miles

Distance travelled by car per liter = 10.5 miles

The number of liters will be obtained by dividing the total distance by distance travelled in one liter.

So,

[tex]number\ of\ liters = \frac{163}{10.5} = 15.523\ liters[/tex]

2. Cost for petrol:

Cost of petrol per liter = 138.9 pence per liter

Then the total cost of petrol will be:

[tex]Total\ cost = 138.9*15.523 = 2156.1447 => 2156.2\ pences[/tex]

3. Time taken for journey

Distance travelled in an hour = speed = 50 miles per hour.

The speed is given by the formula:

[tex]speed = \frac{distance}{time}[/tex]

Putting the values

[tex]50 = \frac{163}{t}\\t = \frac{163}{50}\\t = 3.26\ hours[/tex]

It will take: 3 hours and 0.26*60 = 15.6 minutes => 3 hours 16 minutes

Hence,

The answers are:

Answer: 2.5

Step-by-step explanation:

Given the relationship between month since plant was bought t and plant height H ;

t

0.5

3

5

H:

17.25

23.5

28.5

Using the online regression calculator, the regression model obtained is :

y = 16x + 2.5

Using this model, we can obtain the height when t = 0 ; this will give the height at the time of purchase of the plant. Therefore, at x = 0

y = 16(0) + 2.5

y = 0 + 2.5

y = 2.5

Hence, height of plant = 2.5

Answer:

substitute -4 for x

Step-by-step explanation:

A function assigns the value of each element of one set to the other specific element of another set. The value of the function when the value of x is -4 is 92.

A function assigns the value of each element of one set to the other specific element of another set.

Given that F(x)=3x²-10x+4, therefore, the value of the function can be calculated by substituting the value of x as -4.

Therefore, the value of the function when the value of x is -4  can be calculated as shown below,

F(x) = 3x² - 10x + 4

F(-4) = 3(-4)² - 10(-4) + 4

        = 3(16)  + 40 + 4

        = 48 + 40 + 4

        = 92

Hence, the value of the function when the value of x is -4 is 92.

Answer:

x is -9 is an extraneous solution

Step-by-step explanation:

Given the expression

x/4 = x²/3(x+3)

We are to find the value of x

Cross multiply

3x(x+3) = 4x²

3x²+9x = 4x²

3x²-4x² = 9x

-x² = 9x

-x = 9

x = -9

Hence the value of x is -9 is an extraneous solution

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

No,

Delilah is not standing with Petro after she walks 8 units to its left.

The position on the map is not the same.

The coordinates of Delilah and Petro is not the same.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

The following coordinates.

Delilah is standing at (10, -13).

Pedro is standing at (18, -13).

Delilah walks 8 units left.

This means,

The coordinates of Dellah will be,

(10, -13) → (10 - 8, -13) = (2, -13)

In order for Delilah to stand together with Pedro both their coordinates must be equal.

Delilah coordinates = (2 , -13)

Pedro coordinates = (18, -13)

Thus,

No,

Delilah is not standing with Petro after she walks 8 units to its left.

The position on the map is not the same.

The coordinates of Delilah and Petro is not the same.

Answer:

It is in fact 113 I'm just here to explain

Step-by-step explanation:

Basically M6 and M7 must make a staright line(180) and since we already know that M6 is 67 we just have to subtract 67 from 180 to get the answer we are looking for. ( it would be the same process if we were looking for M1 (113) and also if you had the measure of M1 you would have had your answer to M7 because they are vertical angles therefore making them congruent

Answer:

Length = 18 inches

Width = 12 inches

Step-by-step explanation:

Let the Length be 3x and width be 2x

Area= Length*Width=216 inches squared

216=3x*2x

216=6x²

x²=216/6

x²=36

x=√36

x=6 inches

Therefore

Length = 3x = 3*6 = 18 inches

Width = 2x = 2*6 = 12 inches

Step-by-step explanation:

See attachment for triangle

The relationship between length x, length 24 and angle 30 is as follows:

[tex]\cos(\theta) = \frac{Adjacent}{Hypotenuse}[/tex]

In this question;

[tex]Adjacent = x[/tex]

[tex]Hypotenuse= 24[/tex]

[tex]\theta = 30[/tex]

Substitute these values in the above expression,

[tex]\cos(30) = \frac{x}{24}[/tex]

Multiply through by 24

[tex]24 * \cos(30) = \frac{x}{24} * 24[/tex]

[tex]24 * \cos(30) = x[/tex]

Using the mid-point formula

[tex]m\:=\:\left(\frac{x_1+x_2}{2},\:\frac{y_1+y_2}{2},\:\frac{z_1+z_2}{2}\right)[/tex]

Using the mid-point formula

[tex]m\:=\:\left(\frac{x_1+x_2}{2},\:\frac{y_1+y_2}{2},\:\frac{z_1+z_2}{2}\right)[/tex]

given

(x₁, y₁, z₁) = (1, 2, b) = P

(x₂, y₂, z₂) = (c, -7, 4) = Q

m = (x, y, z) = (-3, a, -1) = R

substituting the value of (x₁, y₁, z₁) = (1, 2, b) = P,   (x₂, y₂, z₂) = (c, -7, 4) = Q, and m = (x, y, z) = (-3, a, -1) = R in the mid-point formula

[tex]m\:=\:\left(\frac{x_1+x_2}{2},\:\frac{y_1+y_2}{2},\:\frac{z_1+z_2}{2}\right)[/tex]

[tex]\left(x,\:y,\:z\right)\:=\:\left(\frac{1+c}{2},\:\frac{2+\left(-7\right)}{2},\:\frac{b+4}{2}\right)[/tex]

as (x, y, z) = (-3, a, -1), so

[tex]\left(-3,\:a,\:-1\right)\:=\:\left(\frac{1+c}{2},\:\frac{2+\left(-7\right)}{2},\:\frac{b+4}{2}\right)[/tex]

Determining 'c'

-3 = (1+c) / (2)

-3 × 2 = 1+c

[tex]1+c = -6[/tex]

[tex]c = -6 - 1[/tex]

[tex]c = -7[/tex]

Step-by-step explanation:

(1,0) and (9,1)

The graph of a function f is the set of all points (x,f(x)). Any point on the graph satisfy the equation of the graph. To check whether a point lie on a graph we need to put the x value and y value of the point to the equation of the graph and check the LHS and RHS . If LHS is equal to RHS , then this point lie on the graph.

The given equation of graph is y=log₉(x)            ...........(i)

Putting both the points on the LHS and RHS of (i) we get

For point (1,0) , LHS = 0 and RHS = log₉(1)=0

Therefore LHS=RHS for the point (1,0).

For point (9,1), LHS= 1 and RHS= log₉(9)=1

Therefore  LHS=RHS for the point  (9,1).

Therefore (1,0) and (9,1) lie on graph of equation (i).

Putting both the points on the LHS and RHS of (i) we get

For point (0,1), LHS=1 and RHS=log₉(0) is undefined

Therefore LHS≠RHS for the point (0,1).

For point (1,9), LHS= 9 and RHS= log₉(1)=0.

Therefore LHS≠RHS for the point (1,9).

Therefore (0,1) and (1,9) does not lie on graph of equation (i).

Putting both the points on the LHS and RHS of (i) we get

For point (1,0), LHS=0 and RHS=log₉(1)=0.

Therefore LHS=RHS for the point (1,0).

For point (9,0), LHS= 0 and RHS= log₉(9)=1.

Therefore LHS≠RHS for the point (9,0).

Therefore (1,0) lie on (i) but 9,0) does not lie on graph of equation (i).

Putting both the points on the LHS and RHS of (i) we get

For point (1,0), LHS=0 and RHS=log₉(1)=0

Therefore LHS=RHS for the point (1,0).

For point (9,9), LHS= 9 and RHS= log₉(9)=1.

Therefore, LHS≠RHS for point(9,9).

Therefore (1,0) lie on (i) but 9,9) does not lie on graph of equation (i)

Hence, the points (1,0) and (9,1) lie on the graph of y=log₉(x).
